In this dissertation we consider problems related to the singularity analysis of the Ricci flow. We obtain curvature conditions which prevent the Ricci flow on a closed manifold from developing singularities in finite time. These can be viewed as regularity results for the Ricci flow as a weakly parabolic PDE system. We also prove some rigidity phenomena for Ricci-flat manifolds and gradient steady Ricci solitons. In particular, we improve an -rigidity theorem for Ricci-flat manifolds by removing all the volume growth assumptions in its previously known versions. Then we generalize this -rigidity result to gradient steady Ricci solitons with non-constant potential functions.
